Talk:Carbondale mine fire

Uncertainty of start and end years
I'm puzzled as to why we have two possible years given for both the start and the containment of the fire. This wasn't an event in a remote region, this was in Pennsylvania. One would think contemporary media coverage exists that would provide a more definitive year at either end rather than a two- or three-year spread. 136.159.160.5 (talk) 17:03, 5 June 2019 (UTC)

PPM
PPM stands for "parts per million" not "parts per millionth." When I tried correcting this, the editor who made the change claimed I was being a "pedant" and reverted it. Unless reliable sources are brought here to support changing the phrase to "parts per millionth", I am going to revert it back again. If that happens, please do not change it back without first discussing here, per WP:EW. Thank you. -- Puzzledvegetable Is it teatime already?  18:31, 5 February 2020 (UTC)

There is no reason to replace parts per million with PPM. This is only done when the phrase is mentioned multiple times, in which case "parts per million (PPM)" is used the first time and just "PPM" is used all subsequent times. In this article, it is only used once, so there is no reason to switch "parts per million" to "ppm (parts per million)", especially when there is no precedent for putting the abbreviation before the phrase itself. Please do not revert without responding here first. -- Puzzledvegetable Is it teatime already?  19:43, 7 February 2020 (UTC) Edit: Please note the relevant material in the manual of style. -- Puzzledvegetable Is it teatime already?  19:51, 7 February 2020 (UTC)

3O Response: I was surprised to find nearly 400 Google hits for "parts per millionth". (There are 23,000 times as many for "parts per million".) The article Parts-per notation makes no mention of the ordinal parts per millionth, and the only hit for it on en.wikipedia is this talk page. Per the principle of least astonishment, I would strongly recommend using the more common "parts per million". I'll also note that PPM (or ppm) is not one of the which can be given without an expanded form, so best to write it out in full. This is a non-binding third opinion, but I hope it helps! – Reidgreg (talk) 16:23, 12 February 2020 (UTC)
